Laser Epilation - Different Types of Lasers

LASER i.e. Light Amplification by Stimulated Emission of Radiation produces an intense beam of light of particular wavelength  with insignificant dispersion over a short distance. This property is utilized in dermatology to treat various skin disorders.

The laser is not new to electrolysis. When a laser beam is directed at the skin, it is absorbed by the water, naturally occurring pigments like melanin and hemoglobin.

Laser therapy for hair removal enables you to have a more carefree, confident lifestyle, representing a big saving in time and money spent on conventional treatments. Laser hair removal may sound like something out of Star Wars but its the greatest beauty breakthrough since the invention of the blow-dryer.

Lasers have been used for many years for a variety of medical cosmetic procedures including treatment of facial and leg veins, age spots and smoothing fine lines on the face. The laser energy is transformed into heat, which can disable the follicle leaving the surrounding skin unchanged.

This Diode Laser is medically proven to be the safest, fastest & most effective form of hair removal at hand. Through this laser, the permanent hair reduction can be achieved. It has a higher and deeper wavelength and varied repetition rate for speed and a safer penetration level for all different skin types. There is less heating of the skin due to the active refrigeration built into the handpiece to cool the skin down. Through this laser, your skin gets protect from the high intensity of light.

LASER HAIR REMOVAL

When a tissue absorbs laser light, the energy is converted to heat. This heating produces the laser's physiological effect. Most laser hair removal systems are designed to remove unwanted hair through selective absorption of an intense light pulse at wavelengths that are preferentially absorbed by the desired targets (hair follicles) but not by the surrounding tissue.

Several different laser sources can be used for the removal of the hairs. They include Ruby lasers, Alexandrite lasers, Nd:YAG lasers, and Diode lasers.

RUBY LASER:

The Ruby laser is found very effective in the removal of unwanted hairs from the body. It has an output wavelength of 694nm which is very selectively absorbed by melanin. It causes selective damage to hair follicles, minimising injury to the skin.


ALEXANDRITE LASER:

This laser produces laser energy at 755nm, in the red to near infrared portion of the EM spectrum. Same as ruby laser, alexandrite energy is absorbed by melanin in skin and hair follicles. This laser works in a similar fashion to the Ruby Laser.


NEODYMIUM: YTTRIUM ALUMINIUM GARNET: Nd:YAG lasers are solid state lasers that produce invisible light energy at 1064nm. This laser comes in the infrared portion of the electromagnetic spectrum.The ND:YAG lasers can be used in frequency doubled mode to produce green light of 532nm.

The main advantage of the methods of laser epilation is that, the hair slows down its growth, but complete removal doesn't takes place. In all methods of laser epilation, there is the absorption of the energy of electromagnetic waves. In the laser methods, there is the generation of the acoustic waves, which mechanically destroy the structure of the hairs.
